i live on a small lake in big lake area and we usally have otters show up a couple of times a summer. normaly three or four at a time, but once this summer a loner showed up and hung out for a coupe days. i watched him stalk and sneak-attack from below a pair of loons (or greebs). for about an hour he pestered the hell out of the birds, i think he got ahold of them a few times. just wondering if this is typical.
